LexieSoundScore 4.7Grade A

Lexie B3

The Lexie B3 is a mid-priced OTC hearing aid available at $999 that achieves an A grade with a SoundScore of 4.7/5 in our lab testing, ranking #1 among 65 OTC hearing aid devices tested. This behind-the-ear style device delivers category-leading performance across multiple metrics. Speech clarity is a standout strength. In our lab testing, the Lexie B3 scores an excellent 4.5/5 for speech in quiet, measuring 1.73 points above the OTC category average. Speech in noise performance scores 2.5/5—above the category average by 1.02 points, though only mixed in absolute terms at 2.5/5. This pattern reflects the broader challenge OTC devices face in noisy environments while still positioning the B3 as a top performer relative to its category. Music streaming quality is solid at 3.3/5, outperforming the category average by 1.38 points. Own-voice comfort scores a solid 3.0/5, sitting 0.49 points above average. Feedback handling is excellent at 4.6/5, essentially matching the already-strong category average. The Lexie B3 is best suited for consumers seeking top-tier OTC sound performance without prescription hearing aid costs. Those who prioritize speech clarity in quieter settings will find particular value here. Budget-conscious shoppers may want to consider alternatives like the RxEars Rxi, which offers strong performance at a lower price point.

Signia Silk Charge&Go IX

The Signia Silk Charge&Go IX is a premium prescription hearing aid featuring an invisible-in-ear design, currently available at $3,298. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.7/5, ranking #32 of 39 prescription hearing aids tested. This device demonstrates a notable strength in speech clarity for quiet environments, scoring an excellent 4.6/5—well above the category average by 1.22 points. Speech in noise performance is mixed at 2.2/5, though this still edges slightly above the category average. Feedback handling is strong at 4.3/5, providing reliable stability during typical wear, even if it falls just below the category average. The Silk Charge&Go IX has significant limitations to consider. Own-voice comfort scores low at 1.5/5, falling 1.20 points below the category average—a trade-off that may relate to the invisible form factor. Most notably, the device does not support music streaming, scoring 0.0/5 in that metric, which is 2.76 points below the category average. At this premium price point, several competitors deliver substantially higher overall performance, including the Phonak Sphere Infinio (4.98/5) and Oticon Intent (4.83/5). The Silk Charge&Go IX is best suited for users who prioritize an invisible, rechargeable design and primarily need clear speech understanding in quieter settings, while having minimal need for streaming audio content.
